XM Service / Terrible customer service
XM's customer contact center is horrible. They are unable to accomplish simple tasks like the cancellation of service for one of the radios on my account. I spent over an hour being transferred back and forth between various departments but never accomplished the cancellation. They refused to escalate my call to a supervisor. This company is the worst! Once they have your money, they don't care about satisfying your needs as a customer. I would never buy another XM product!
